CrossTalk #4

December 2nd, 2022


December 2nd, 2022

The manufacturing sector accounts for 10 % of Canada’s GDP.  Metal 3D printing has the potential to revolutionize this sector by offering increased design freedoms and customizability, reducing time-to-market, reducing materials consumption, and increasing efficiency.  Listen to professionals talk about what skills are required to work with the next generation of materials and emerging 3D printing techniques for light metals.

Is there a career there for you?

In this discussion, we’ll hear from major players in the additive manufacturing sector.  Learn what skills are required to prosper in this industry and participate in an informal discussion afterward.


Date: Friday, December 2nd, 2022

Time: 3:00 pm Eastern time

Javier Arreguin

Javier Arreguin is the Senior Materials Project Manager that joined AP&C, a GE Additive Company, in April 2017.

Before GE additive, he was involved in various projects supporting the adoption and certification of Additive Manufacturing technologies for Aerospace OEMs, starting from technology benchmarking through to part printing and process characterization. He gained hands-on experience with various powder metallurgy processing techniques such as laser powder bed fusion laser, electron beam melting, powder deposition, powder sintering and hot isostatic pressing. During the last five years, he developed a sound knowledge of metallic powder for the additive manufacturing process. Working at GE impulse me to develop effective project management and product development aptitudes.

In his current role, he oversees specialized research partnerships with key AP&C customers. Part of his objectives are ensuring material optimization and process reliability. As part of his responsibilities, he is in charge of new product introduction for the GE Additive Powder portfolio, working from potential supplier identification and selection to their validation and qualification.

Javier is currently the GE Additive ambassador for ASTM, ISO, SAE-AMS and NADCAP committees for Additive Manufacturing. His background is in Physics and holds master’s and Ph.D. degrees in Materials Science. Javier has thirteen years of powder metallurgy experience and more than ten years with Additive Manufacturing technologies directly.

Paul Rometsch

Paul is currently a Principal Research Scientist with Rio Tinto Aluminium, where he works on aluminium product metallurgy at the Arvida Research and Development Centre in Saguenay, Québec (Canada). He obtained his PhD in Materials Engineering at the University of Queensland (Australia) and has held various academic and industrial positions focused on R&D within the global aluminium industry. This included appointments at Comalco Aluminium (Australia), the University of Southampton and the Luxfer Group (UK), Hydro Aluminium Precision Tubing (Europe and China), and Monash University (Australia). Paul has published widely in the field of aluminium metallurgy and has about a decade of R&D experience with additive manufacturing, both at Rio Tinto Aluminium and previously at the Monash Centre for Additive Manufacturing.
